问题描述
好吧，我进入了石墨和石墨网，并陷入了“异常值：尝试编写只读数据库”错误。我已经在数据库本身上尝试过chmod和chown，而我仍然收到此错误。
文件位于/opt/graphite/storage/graphite.db下，它获得了rwx-rwx-rwx（chmod 777）烫发，我尝试以所有者的身份访问www-data并将其重新放回根目录，从而导致出现相同的错误。 / p>

Exception Type: OperationalError at /composer
Exception Value: attempt to write a readonly database
那是来自error.log：
解决方法
自己解决。不是数据库本身，而是没有写权限的文件夹！
